rhythmbox takes 100%cpu to play ogg

[starox]

When I play oggs with rhythmbox, it takes 100% of one cpu.
I use a powerppc with 2 cpu with Ubuntu Dapper.

[Sebastien Bacher (seb128)]

Thanks for your bug. Does it happen if you use "gst-launch playbin uri="file://path/to/ogg" to play them? Does that happen with all the ogg or only one?

[starox (starox)]

Yes, it's still loading a cpu.

Here is the output of gst-launch, interrupted by a ctrl-c :

Does it happen with all the ogg or only one? Could you get a backtrace?
- gdb gst-launch
(gdb) run playbin uri="file://path/to/ogg"
... ctrl-C
(gdb) thread apply all bt

And copy that to a comment

[starox (starox)]

It happens at least with all my mp3 and ogg. I don't have the problem with mplayer though.
The load is about ~80% system time and 20% user time.
Here is the backtrace.

What audiosink do you use from gstreamer-properties? Could you try changing it?

[starox (starox)]

Using gstreamer-properties, I have autodetect, alsa, esd, oss and custom settings for audio output.
It was on autodetect before.
Alsa and esd load the cpu.
Oss give an error message :
 Error running pipeline 'OSS - Open Sound System': Unable to open device /dev/dsp for writing: Périphérique ou ressource occupé [gstosssink.c(388): gst_oss_sink_open (): /pipeline0/osssink1]

I am using a custom kernel but It behaves identical with ubuntu kernel.
I was thinking about timer issue as it seems an active wait ? maybe dev/rtc problems ?

[Sebastien Bacher (seb128)]

Could you attach the backtrace as an attachment without all the extra lines from the previous comment?

[starox (starox)]

This is a backtrace of gst-launch playing an ogg and taking 100% cpu.
gst-properties is set on 'auto' for audio output.

[Sebastien Bacher (seb128)]

Thank you for your comments, I've forwarded that upstream: http://bugzilla.gnome.org/show_bug.cgi?id=332677

That could be an libasound issue though, Martin any opinion on that?

[starox (starox)]

I forgot my platform : Apple Powermac G5 1.8Ghz - 2 cpus

[starox (starox)]

I've updated my system today, keeping the same kernel, and the problem is gone !

[Dennis Kaarsemaker (dennis)]

Good to hear! I'm closing this bug, feel free to reopen if the bug
appears again.
